1. A portable intermittent pneumatic compression system comprising;
a pumping module, said pumping module comprising a housing containing an air pump having a pump inlet and a pump outlet, a valve having a valve inlet and at least two additional ports including an inflation port and a ventilation port, a power supply, an electronic control unit, and a fluid coupling connecting the pump outlet to the valve inlet; a flexible inflatable wrap containing an inflatable bladder and having an outer surface and an opposite inner surface that abuts a wearer when the wrap is worn, said flexible inflatable wrap including a first fluid port in fluid communication with the inflatable bladder, and a second port that extends through the wrap to the inner surface, said second port not being in fluid communication with the inflatable bladder; said inflation port of the valve being fluidly coupled to the first port of the inflatable wrap, and the ventilation port of the valve being fluidly coupled to the second port of the inflatable wrap; said valve being switchable from an inflation state in which air may flow from the valve inlet to the inflation port through the first port of the inflatable wrap and into the bladder, to an inflated state in which air does not flow through the inflation port, to a ventilation state in which air may flow from the bladder through the first port and through the inflation port through the ventilation port and through the second port of the inflatable wrap and through the inner surface of the flexible inflatable wrap. |
